Working Principle of Infrared Diode Receivers

The working principle of an infrared diode receiver is based on the photoelectric effect. When an infrared signal is received by the receiver, the infrared diode will convert the infrared energy into electrical energy. The following is a detailed explanation of the working principle:

1. Infrared signal transmission: The infrared signal is generated by the infrared emitter, which is usually an LED or a laser. The infrared signal is transmitted through the air or other medium to the infrared diode receiver.

2. Infrared signal reception: The infrared diode receiver is composed of an infrared diode, a photodiode, and a signal processing circuit. The infrared diode is used to convert the infrared energy into electrical energy, and the photodiode is used to convert the electrical energy into a current signal.

3. Signal processing: The current signal output by the photodiode is a weak signal. The signal processing circuit is used to amplify and filter the signal, so that the output signal can meet the requirements of the application.

4. Output: The output signal of the infrared diode receiver is an electrical signal that can be easily processed and recognized by the control circuit. The control circuit can then execute the corresponding operation according to the received signal.
